WILLIAM HENRY GARDNER, OF SUTHERLAND, SASKATCHEWAN, CANADA.

WINDOW-VENTILATOR.

Application filed October 14, 1912, Serial No. 725,607.

To all whom it may concern Be it known that I, VVILLIAM HENRY GARDNER,of the village of Fsutherland, in the Province of Saskatchewan, Canada,have invented certain new and useful Improvements in Window -Ventilatrs,of which the following is the specification.

The invention relates to a ventilator in sertible in any window framebeneath the usual top sash thereof and the object of the invention is toprovide a comparatively inexpensive, durable and easily operated devicewhich can be quickly inserted in a window frame and which will allow aroom to be ventilated without having a direct draft as is usual when theunder sash of a window is raised, the ventilator being constructed sothat it does not exclude the light.

With the above objects in view the invention consists essentially in thearrange ment and construction of parts hereinafter more particularlydescribed and later point ed out in the appended claims.

Figure 1 is a perspective view of the device as applied in a windowframe, part of the frame being torn away to expose construction. Fig. 2is a vertical sectional view through a frame fitted with my ventilator.Fig. 3 is a plan view of the ventilator. Fig. a is an enlarged detailedperspective View of one of the upper corners of the ventilator. Fig. 5is an enlarged detailed vertical sectional view through a por tion ofthe top and inner frames showing the bolt and clamping plate.

In the drawings like characters of reference indicate correspondingparts in each figure.

1 represents the window frame of which 2 and 3 are the side members, athe upper or top cross member and 5 the sill.

6 represents the usual upper sash located in the frame between thebattens 7 and supplied with the usual glass 8.

9 represents my ventilator which is inserted within the frame betweenthe lower edge of the sash 6 and the sill 5.

The ventilator is now described in detail: 10 represents an outersubstantially rectangular open frame formed in the pres ent instancefrom angle irons of a width which will fit snugly in between the members2 and 3 of the window frame and between the lower edge of the sash 6 andthe sill 5. A substantially rectangular horizontally disposed open topframe 14: is per- Patented Jan. 5, 1915.

manently secured to the upper edge of the outer frame and comprises inthe present instance angle iron side bars 15 and 16 and angle iron endbars 17 and 18 suitably connected, the side bar 16 actually forming theupper cross member of the frame 10. 19 is a substantially rectangularinclined inner frame formed in the present instance from side angle ironbars 20 and 21 and end angle iron bars 22 and 23 suitably connect ed.This frame is fitted with a pane of glass E i and has the side bar 21connected by hinges 25 and 26 pivotally to the lower side of the outsideframe 10. Extending plates 27 ant 28 are secured to the upper side ofthe inner frame and are provided with suitable slots 29 receiving shortpermanent bolts 30 extending from the top frame 1%. The bolts areprovided with wing nuts 31 so that one can swing down or open the innerframe by removing the wing nuts and allowing the plates to escape fromthe bolts. Although I have described a particular means for releasablyfastening the inner frame to the top frame it will be understood thatany other convenient device could be employed to equal advantage. 32 isa vertically disposed transparent door pivotally secured at 33 to thebottom side member of the frame 10 such door being arranged to close inagainst the said frame. The door is formed in the present instance fromT-iror. side and end bars 84 and is fitted with a pane of glass 35.

36 is a normally horizontally d'sposed substantially rectangulartransparent door pivotally secured by hinges 37 to the upper side memberof the frame 10. This door is formed in the present instance from angleiron side and end members 38 suitably connected together which memlflerscarry a pane of glass 39. The door is arranged to close the open centerof the top frame. When closed it is received within an open side frame40 disposed on the top frame. A cord, rope or such like fl is suitablyconnected to the inner side of the door 36,

which cord passes upwardly and around a suitable pulley 4-2 suspendedfrom the cross member f of the frame. A suitable hand grip 41-3 islocated on the free end of the cord. The doors and 36 are connected bytwo spring wires or rods ift and ett the upper ends of the wires beingpermanently fastened to the inner edge of the door 36 while the lowerends are pivotally secured at 45 to the upper edge of the door 32. Therods pass slidably through guide plates 46 and 47 permanently secured tothe top frame 14. This arrangement is such that When one draws on thecord to raise the door 36 he also draws in the door 32 on account of thewire connection.

48 is a catch piece or dog pivotally secured to the inner side of theframe 10 at the top and arranged to catch over the upper edge of thedoor 32 and holds the same closed. A spiral spring 49 has the lower endthereof fastened to the free end of the dog and the upper end fastenedto the adjoining side of the top door. Accordingly when one raises thetop door as above described the spring 39 draws or pulls on the upperend of the dog and initially releases it from the upper edge of the door32 thereby permitting the door to open. It is explained that during theinitial opening of the top door, the spring rods bow sufficiently toallow it to partially open While the door 32 remains closed. The topdoor only needs to be opened sufficiently to expand the spring 49 andraise the catch at which time the door 32 will be free to open as thedoor 36 is raised.

lVith this device applied on a window it will be seen that the draftinstead of passing in a horizontal direction through the window will bedeflected upwardly passing as it does through the frame 10 and throughthe frame 14.

A screen can be provided with this device for excluding flies or otherinsects which screen would simply need to be stretched over the outerside of the frame 10.

I wish to point out that the ventilator can be used to great advantagein railroad cars where it is desirable to have a ventilator which willgive an indirect ventilation and at the same time exclude cinders anddust. In most instances where the ventilator is applied the V-shapedopening appearing at the ends of the ventilator between the frame 10, 14and 19 would not need to be closed as the side members 2 and 3 of thewindow will effectively close these. They can however if desired beclosed by plates or panes of glass as will readily be understood.

What I claim as my invention is:

1. The combination with the side members, sill and upper sash of awindow, of

, an open upright outer frame insertible between the side members thesill and the sash, a horizontally disposed open top frame car- I ried bythe outer frame, an angularly disposed inner frame connecting the innerside of the top frame and the lower side of the bottom frame said innerframe carrying transparent material such as glass, an adjustable gatenormally closing the opening in the top frame, a second gate pivotallysecured at its lower side to the outer frame and designed to normallyclose the opening in said frame and means connecting the gates causingthem to open and close together, as for the purpose specified.

2. The combination with the side members, sill and upper sash of awindow, of an open upright outer frame insertible between the sidemembers the sill and the sash, a horizontally disposed open top framecarried by the outer frame, an angularly disposed inner frame connectingthe inner side of the top frame and the lower side of the bottom frame,said inner frame carrying transparent material such as glass, anadjustable gate normally closing the opening in the top frame, atransparent second gate having the lower side thereof hinged to thelower side of the outer frame, spring rods carried by the former gateand pivotally secured to the second gate and releasable means lockingthe second gate closed, as and for the purpose specified.

3. The combination with the side members, sill and upper sash of awindow, of an open substantially rectangular outer frame insertiblebetween the side members sill and sash an open substantially rectangularinwardly extending top frame secured to the upper side of the outerframe, an inclined substantially rectangular open inner frame pivotallysecured to the lower side of the outer frame, a transparent materialclosing the opening in the inner frame, means securing the upper side ofthe inner frame releasably to the inner side of the top frame, asubstantially rectangular transparent horizontally disposed top gatepivotally secured to the outer side of the top frame and normallyclosing the opening in said frame, a vertically disposed substantiallyrectangular transparent gate having the lower side pivotally secured tothe lower side of the outer frame and designed to normally close theopening in said outer frame, spring rods connecting the inner side ofthe top gate with the upper side of the vertically disposed gate, guideplates carried by the top frame and receivingthe rods slidably, a dogpivotally secured to the outer frame centrally at the top and normallyholding the vertically disposed gate closed, a spiral spring connectingthe dog with the top gate and means for raising or opening the top gate,as for the purpose specified.
